For the first time ever, neurophysiologists of KU Leuven, Harvard and the University of Kyoto have succeeded in reversibly disabling a connection between two areas in the brains of primates while they were performing cognitive tasks, or while their entire brain activity was being monitored. The disconnection had a negative impact on the motivation of the animals, but not on their learning behaviour. The study, which was published in Neuron, may eventually lead to more targeted treatments for certain brain disorders.
